Abstract (en)

[origin: EP0695911A1] A gas burner (5) of the type in which an inflammable mixture is caused to flow out of a diffuser (7,8...20) formed of a plurality of parallel slits (21,22,33,34) separated by grid elements and distributed into a pair of grids separated by an elongate screen (37) extending between the two grids, comprising at least one elongate slit (52,53,61,66) extending perpendicularly to said screen (37) through the breadth of said grid pair, perpendicular to the screen (37), near the grids and adapted to recover the relative dimensional variations of said screen (37) and the grid elements brought about by differential heatings of the screen and the burner (5) walls surrounding the diffuser. <MATH>
